I'll clarify a few more things to reply to various comments raised in thsi<br>
thread:<br>
- I never said inclusive is 60% of the total. I said (you can check my<br>
slides at the review) that TRAINS are 60% of the cooked file, and<br>
inclusive is 75% of the trains. This is the info Zhiwen passed me before<br>
the review. The trains were 20% of the cooked data in the spring.<br>
- the train we call "ndvcs" also includes pdvcs<br>
- we are planning to put a Q2 cut, as I said previously, to reduce the<br>
dvcs train size.<br>
<br>
FX, we haven't analyzed yet any of these outbending data (as no cooking<br>
besides calibration one was done), so I don't have a reply to your last<br>
question yet.<br>
<br>
Best regards,<br>
Silvia<br>
